Questione giuridica chiave
Whether the cantonal government could approve a municipal land-use plan without a municipal resolution and without replacement proceedings.
Decisione estratta
No. A municipal plan must first be adopted at municipal level; if the commune defaults, the canton may act only through the statutory replacement procedure, including publication and objection proceedings by the department.
Motivazione estratta
Genehmigung presupposes a prior municipal decision. The government may correct obvious planning errors or, in case of municipal default, itself enact or amend the plan only via the replacement procedure. Here that procedure was not followed.
